Syntax:
b2dShowProfiler:Void(enable:Int)
Void
Shows or hides the built-in profiler panel.
Takes enable (True to show, False to hide).
Shows a small panel in the top right corner (drawn with IGI, so it sits on top of everything and can be dragged anywhere) with:
• FPS, and the frame time in ms (average, best and worst over the last second)
• a graph of the last 120 frame times, where a stutter shows as a spike
• CPU: the time your program's own code took each frame (from the start of the loop to b2dFlip, not counting time spent waiting for the screen)
• GPU: the time the graphics card took to draw the frame. measured exactly, with GPU timestamps
• Draw calls: how many batches the frame was drawn in
• any sections you time with sysProfileStart / sysProfileEnd, with their ms and share of the frame
The figures are averages over the last second and update once a second. The same numbers can be read in code with b2dGetFrameTime, b2dGetGPUTime, b2dGetDrawCalls and sysProfileTime, whether the panel is showing or not.
